According to Feng & Weinberg:

Approximately 500 bacterial species reside in the oral cavity. Of these, 415 species are estimated to be present in subgingival plaque. Specifically:

"A. actinomycetemcomitans has been strongly implicated in localized aggressive (juvenile) periodontitis
Likewise, bacteria such as P. gingivalis, A. actinomycetemcomitans, Tannerella forsythia (formerly, Bacteroides forsythus), Treponema denticola, and Eikenella corrodens have been associated with chronic (adult) periodontitis."

You are correct, it is a correlation, not a causation. I think I mentioned that in the disclaimers.

It is really hard to control for all the variables (price, motivation of seller, location, who the listing agent knows, what style of home is hot), but all other things being equal, it's better to have more photos for a listing. In fact, since it is one of the easiest things to control (it's a lot easier to snap 25 photos than change the price point of a house) I'd argue it is one of the things home sellers should expect.

Would love to hear your suggestions on making this more rigorous. Off the top of my head, it'd be interesting to list a set of same homes twice, once with few photos and once with many photos, and see what the difference in response was. Unfortunately, that is a bit beyond my scope for the time being.

There are no project managers. Everyone is a manager. Literally. You're all responsible for the pieces of the product you're working on in equal terms.

We of course have "primary responsibility people" who are sort of shepherds of various features, and inevitably leaders emerge from among the pack. But we don't have anyone who simply "manages" things.

Our structure is able to withstand this due to the way we structure our internal teams. We're constantly tweaking how we do that, but by keeping the teams small, strategic decisions close to the people who are actually executing them, and retaining intense focus on one piece of the GitHub Product™ (which could be anything from a feature to "performance" to "making GitHubbers' lives easier" to "making us more money"), it makes things run smoothly without some sort of overlord forcing it.

Effective Personal Learning Time In Any Classroom
The program we used for "keyboarding" class required two spaces, too. (This was in 1998, but the program looked like something from the '80s.) The teacher had me evaluate a newer program (that looked more "Windows 95-ish") later in the year and it required a single space. I made a lot of typos that day.

I can't remember what my college course required because I only had to go five or six times to prove my proficiency. (Yes, my university's computing program required a typing course because they had students that couldn't touch type.)
Or how about experimental science? Get some human teeth (probably not difficult or expensive for a dentist), weigh them, plunk them in each liquid, let them sit for a week, see which ones lost the most mass.

Obviously scientific rigor would require several experiments to smooth out the variances in individual tooth quality and original composition, but it seems like that would come to a more definitive conclusion.
Wow, that's a pretty sweet list right there. Thanks!
Placing that on a thank you page wouldn't be as effective. You have already payed and laziness is a major factor. I think that the middle of paying process is the best spot to place it. It doesn't need to be so big and intrusive, maybe just a checkbox placed above the "Checkout" button would do the trick and still get a lot of conversions.

Um...by definition, the CEO, who sets the company's initiatives (including initiatives to kill other initiatives) and holds the "buck", so to speak, cannot be the chief dissenter, in the same way that the Emperor cannot be the leader of the Rebel Alliance. When Steve Jobs was CEO, the chief dissenter would've been someone who pointed out that the iPhone4 antennae issue should not be glossed over.
Doom was the reason for building my first PC. Anyway, many years later, I read and studied doom source code, mostly to see how the game engine worked. I had it printed out on paper and read it line by line and found it to be very readable, and even entertaining.
This offer undermines the reason for having options (building loyalty among employees in lieu of high pay at a time when the company can't afford high salaries). To me, giving away options to non-employees is the sign on an inexperienced company.
That's cute, but your loop stutters. If you're going to loop a sample, make sure you understand musical time first.
The idea of killing bad ideas might save a company from wasted resources and effort, but one would need to exercise caution or end up discouraging innovation. One would need to communicate effectively and subtly about the reasons why an idea is not good enough.

Note that the measurements are often cited per passenger. Part of the spat between Boeing and Airbus over their next gen ~150 seat passenger planes (737max & A320neo)[1] is over how many passengers are used in the calculations (maximize for your own plane, minimize for the other guy). To get an idea of how the argument goes see this article starting in the "war of words" section which gives a good idea of all the factors making up the cost of flying: http://www.aspireaviation.com/2012/07/20/boeing-737-max-ups-...

The efficiency improvements come from all over the place including dealing with wing tips (fences, winglets, "sharklets"), weight reductions (lighter materials, redesigned components) and engines (weight, gearboxes, compression ratios).

The plane manufacturers and engine manufacturers are constantly doing tweaks to give improvements, usually managing around 1% per year. Search for "performance improvement package" to see numerous press releases and articles.

In the future there are blended wing bodies and open rotor engines that have another leap in efficiency.

[1] The tradeoffs are very similar to what we see in the IT industry. For example the 737 is lighter and sits lower to the ground. That means it can't use larger diameter more efficient engines. And makes it more efficient for shorter routes due to less weight, but the heavier higher A320 can then be more efficient over longer routes. Every change made involves retooling and recertification so it isn't a simple decision to just do everything possible. And newer better planes effect the residual values of older planes which makes lessors potentially less likely to buy your newer planes due to economic uncertainty. There was a lot of debate and speculation about re-engining the existing models, re-winging too, fuselage material changes etc.
Clearly the answer then is to kill all the humans.

I love the thought of using more targeted ECT [1] to do this. It makes me wonder if something similar could replace almost all of the other uses for ECT while removing a decent amount of the side-effects given the focused nature of this. One of the biggest of which that I'm aware of is that it can cause severe memory loss, whether it deals with the underlying problem or not.

Certainly there are business models where making the source available doesn't really impact your business negatively. For example, my team makes a lot (almost all, really) of the tools we develop for analyzing security intelligence available as open source, because we compete on the intelligence (data), not the tools themselves.

My experience with women in technology matches the author's but I'll also add that I don't understand why the women in an office together are so cut-throat and brutal towards each other.

If you're trying to answer the question of why there are so few women in IT related roles, the best argument I've heard is that only men are stupid enough to accept the life-style often required by those positions. Sounds plausible to me.
Actually I can't eat aspartame because it severely upsets my stomach, so I need to avoid it completely. Even things like chewing gum with aspartame cause my stomach to get really upset. I think the best solution is simply not eat as much sugar as possible. I was on South Beach diet several years ago, and I actually lost 20 lbs in 5 months, so maybe I will do something similar.

Funny. Being a newer-bie into the tech world, this arena has so much more to offer than just straight coding, which I think is like learning a language - as intelligent as learning French, Spanish, or any other. And more crafting the code to produce an awesome product - front end or back end is pretty thrilling. Especially for people who like instant gratification, which includes lawyers, teachers, and others in non-boring and dull communities.

According to another article [1], this application won't be available through the App Store, only the iOS Developer Enterprise Program, which means that Apple doesn't need to approve the app to get it to run on the iPhones/iPads of a company.

This means it probably uses private API's, because if this was not the case, we would have seen remote control apps like this before in legitimate channels such as the App Store.

In the past 6 months I gave up my iPhone 4S and tried out a few Windows Phones and a Samsung Galaxy S2 (with Gingerbread). I'm very happy with the iPhone but I thought that I would see what's out there before purchasing an iPhone 5. I have to say that by far the Galaxy S2 was my least favorite phone; I could barely stand to use it for a day. This isn't a comment on Android or even the S2. I'm willing to believe that my tastes are atypical and I believe that the phone was usable. I learned that people value certain things over others. Perhaps iPhone owners value something that you yourself do not.

Maybe, maybe not. The in-vivo environment might have many significant differences than some in-vitro setup. What's the role of saliva? of bacteria? of genetics?

Don't underestimate the power of the telephone game (http://en.wikipedia.org/wiki/Chinese_whispers). You need to go back to primary sources. It's very common for papers in software engineering, for instance, to confuse qualitative statements from earlier papers with empirical results.
Agreed. Or, what about investing in yourself and your own venture? Isn't that what entrepreneurship is about?
As a child, my dentist also warned me about Mountain Dew and gave a specific reason - the presence of ethylenediaminetetraacetic acid (EDTA), used as a stabilizer.

His theory was that it would chelate the calcium out of your tooth enamel.

Sounds like a bit of dentist lore that gets passed around. Maybe because they use EDTA during root canals to prep the area.
The spatial enhancements are pretty exciting. You can support a lot of interesting things when search can be polygon queries against polygon data. WKT is a pretty fatty format though.

Yes I do, and greatly prefer it. Just as the written word is more readable in a proportional font, code is too. And more of it fits on the screen!

The only thing that doesn't work in a proportional font is column alignment tricks. (Basic indentation works fine.) That problem is easy to solve by not using column alignment at all. I find code easier to read and much easier to maintain when it doesn't use column alignment. When reading someone else's code that does use column alignment, I just switch to a monospaced font for that file.

I wrote on this at more length here:

http://news.ycombinator.com/item?id=4625340

If you're heavy into column alignment styles as in the examples from that comment, then a proportional font won't be for you. But if not, give it a try. It may seem strange at first but give yourself a chance to get used to it. You may find you like it, and if not, no harm done.
I've learned that my passive income sources have become nonexistent and going into the biz. That's to be expected in the early years of a startup. If anyone has other advice if I were to have pennies to save, do share.
This looks awfully similar to the idea I had since 2009. I never got close to implementing it but I also intended to target Clojure and then Javascript. However I thought about it more in the sense of a nicely structured global open source library. The smallest unit of such a library would be a lisp form. There would be dependency management, version control, documentation and tests for each form. It would be then possible to query the library in plaintext queries like "SHA algorithm" or "vector 3d". The user would be then presented a list of the forms. By looking at the docstrings and tests of the forms the user would be able to choose the most fitting one. Checking out a form would automatically fetch all the forms it requires.

It is nice to see a similar idea actually implemented.
I'd like to throw in the minor nitpick that stretchable/capped images are not iOS 5+, but in fact date back to iPhoneOS 2.0, with -[UIImage stretchableImageWithLeftCapWidth:topCapHeight:]

I think that there is an important difference between suits and dresses. Suits are purely formal attire whereas dresses are formal, but are also designed to present the wearer as sexy. I don't think that there is any mens attire that is analogous to a dress. Anything that a man can wear that is revealing or sexually suggestive is really casual (eg. shorts and no shirt on a beach) or really cheesy/sleazy (eg. deep v-cut t-shirt and super tight pants).

Ask HN: Can I visit your startup in SF?
Hi there,

My name is Max, I'm a cofounder at Kera, and we're from Toronto. We started Kera to teach the world how to use software.

Cameron (one of my cofounders) and I are coming to SF the week after next (Oct 22-26) so we can make new friends and learn how companies like yours are educating and onboarding new users. We're also looking for advice about building our startup. If you're doing something interesting, have an awesome company culture, or just like hanging with Canadians, we'd love to meet you.

Any referrals or introductions are more than welcome.

You can find out more about Kera here (http://kera.io), and we can be found at @maxcameron & @camwest on twitter.

Thanks in advance,

Max

I don't think it's bad faith at all. They're up front about what tools the system is built on. It's more about whether it makes the most sense for you to build and host something like this yourself, or pay for what you use on a service that someone else runs for you. There are pros and cons to each, of course, but I think there are a lot of situations where the latter is going to be better.

One example being: if I was building a new product and wanted to add some reporting/exporting features, I would much rather use a service like this. Document conversion is just infrastructure for those features, and so any time I spend setting up my own system for that is potentially wasted time until I can prove that the features are a success.
good luck guys!
I use Eclipse (now that I no longer have an IntelliJ license) for doing heavy-duty Java, but if I can get away with it, I prefer to do things in MacVim. Eclipse is just too clunky feeling when I want to do simple text editing tasks; it totally throws me out of my flow. That's why I'm on HN right now, as a matter of fact. So clearly, I am not an unbiased observer. That said: have you tried Pathogen/Vundle? Vim plugin management these days is light-years better than the equivalent Eclipse nightmare (I've given up on about half my Eclipse plugins as things constantly break).
Similar to how in computing the 80s is like a millennia ago, skydiving has changed dramatically since the 80s in regards to both equipment and the skills on which skydivers concentrate.

As for behavior, people intentionally increase their speeds on landing for more fun, wingsuiting is fairly common, and there are sub-disciplines of freefall were people spend the entire portion of the skydive upside down.

Darpa’s New Director Wants to Keep the Skies Under U.S. Control
Status Report, and Priorities for Fall 2012
The misconception about meditation is that it requires one to give up everything and sit silently. This is not true in its entirety as it depends on how one interprets the word "meditation".

The meditation does not necessarily require you to give up one thing for the sake of another. The goal of the meditation is to "be in awareness" and you can achieve this same goal by being alert and aware with any activity your find yourself doing at any given moment. For example...

You are washing dishes but you are not really washing dishes because your mind is wandering with thoughts on what you need to do tonight at the place you need to visit. By the time your dishes are done, you have already planned for your future as your mind kept you busy with the thoughts of the future while you forgot what you were doing in the present (which is, washing dishes, which you really didn't).

The meditation is to be-in-present with whatever activity you do and love to do. If you had washed your dishes with full alertness and awareness, you would have achieved the same goal of meditation.

Let's go even further with another example.

You love to play music as your passion (or dance, or paint, or fill in the blank activity here) but you don't get enough opportunity in the day to do what you love to do more with passion. When you dance or sing or play music or run or exercise, you get the opportunity during that activity to forget yourself in the act (the subject merges into the object) and you become one with the reality, or you transcend that favorite activity by merging your self into it. That moment of transcendence is meditation, and you should find more opportunities to be in that meditation, in those moments.

Now, I am not suggesting that the type of meditation mentioned at the source is wrong or ineffective. What I am suggesting however is that people don't need to get stuck with one type of explanation of meditation because ultimately you can achieve the same goal by shifting the focus a bit.
There's a cost to everything. One of those costs is hiring someone (or some company) to do testing -- something that's especially hard in mobile since it's not a mature technology.

Giving away options is just another way to pay that cost. For a small company with few employees, the ROI is pretty huge.

I'm not saying it's right or wrong, just that it's an innovative solution to a tough problem that works well within the constraints that a very young company has.
